Hi, Config : RasPi 4B Rasbbian 64

I have no more the issue with this patch and previous Raspbian release :-)

**Since I went to last release :Linux XPiRasp4 5.10.4-v8+ #1389 SMP PREEMPT Wed Jan 6 13:52:18 GMT 2021 aarch64 GNU/Linux I have again the same isue (despite I patch manually the MakeFile with Makefile.patch (it was already almost good))

Any workaround ? Regards

Sorry for the late reply. This is a kernel related issue. Raspbian (PiOS) 64-bit support for external drivers is, shall we say, in development. The 32-bit support across multiple releases is fine. I suffered the same problem and decided that life would be calmer sticking to 32-bit for the time being.
